Different power tool batteries have different BMSs, as well as connector to connect to their brand of power tools. So the only thing that can be modular between one brand and the other is the actual cells. I know that there are converters to change for exmaple the Makita connector to a Milwaukee...
Hello Freinds
I have a power tool BMS whose rated continuous discharge current is 35 A. So per Matador's ampacity table that is cited on these forums in many places, 0.1 mm thick by 10 mm wide strip, 13 of them stacked would give me 36.48 A.
Now the B- and B+ holes within the PCB, can't fit...
I have a couple of questions with regards to using different model cells of different capacities within a single battery pack, but the same chemistry and at the same voltage. Note I am NOT suggesting that anybody does this or does anything unsafe. I'm simply asking a question to understand a...
I see this formula for ampacity of busbar for DC current
I_CCC = K*busbar width*bus bar thickness
Is it really this simple? Where K is a constant depending on if you are using copper or aluminum. This equation seems to simple to me. Additionally, I can't find anything with regards to the...
Thank you for the replies! I'm planning on using plain nickel strips.
I think you might be right about length not being used for resistance calculations for DC circuits. Could you please elaborate a bit on why the length is left out of the resistance calculations though please?
I was always...
So I've gone through the Copper Bus Bar book. In my case, I'm using a battery and not an inverter. So DC only.
Section 2.0 Current-Carrrying Capacity of Busbars
Section 2.2.2 Heat Generated by a Conductor
Appears to be the section of interest.
So in my theoretical case of width of 5 mm width...
So I've made some more progress.
Equation 1 from this source: http://www.electrician2.com/articles/ampacity.htm
The term "thermal resistance" is used in this source. Trying to search for "thermal resistance of air" does not lead to much. The lack of parantheeses for units of measurent of...
I'm simply trying to understand how to select nickel strip for my battery pack. Note that I'm just simply trying to understand the math here only and the concepts behind selecting nickel strips, and nothing more. I'm not suggesting anyone do anything unsafe.
I'm building a 5S3P Li-Ion pack from...
